Aldehydes reduce dichromate from the +6 to the +3 When heated strongly, it decomposes with the evolution of oxygen. 4K 2Cr 2O 7 → 4 2CrO 4 + 2 2O 3 + 3O 2 When an CrO 2− 4). For example, potassium chromate is produced industrially using K 2Cr 2O 7 + 2CO 3 → 2K 2CrO 4 + CO 2 The reaction is reversible. Treatment with cold 3): K 2Cr 2O 7 + 2H 2SO 4 → 2CrO 3 + 2 4 + H 2O On heating with concentrated acid, oxygen is evolved: 2K 2Cr 2O 7 + 8H 2SO 4 → 2 2SO 4 + 2 2(SO 4) 3 + 8H 2O + 3O 2 Uses [ ] Potassium dichromate has few major applications, as the sodium salt is dominant industrially. The main use is as a precursor to Cleaning [ ] Like other Construction [ ] It is used as an ingredient in Photography and printing [ ] In 1839, These discoveries so...
